Abstract: A laboratory study of the effects of an ice cover on flow and alluvial-sediment transport processes in alluvial channels is described. The experimental study consists of laboratory flume experiments with free-surface flows and flows with simulated ice covers of three different roughnesses. The effects of an ice cover on flow depth, velocity distribution, bedload transport, bedform topography and bedform geometry are considered. The addition of an ice cover is seen to increase depth, reduce mean velocity and reduce bedload transport.
